r.quantile prints quantiles for a specific map, similar to "r.univar -e" (but vastly more efficient for large maps). r.statistics3 calculates quantiles for a cover/base combination, and optionally generates a reclass of the base map, similar to "r.statistics method=median" (but more efficient, not limited to integer data, and for arbitrary quantiles). > >>> It seems that r.statistics3 should be renamed to something more > >>> descriptive as it differs functionally from r.statistics > >> > >> It can be used as a substitute for r.statistics method=median, but can > >> calculate arbitrary quantiles.

It should be possible to make r.statistics3 behave like r.quantile in the absence of a base map. -- Glynn Clements <[email protected]> _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
